Hi cfd colleagues,
What are the pressure boundary conditions I have to set for the following boundaries?: 1) Flow entering through a boundary. 2) Flow exiting through a boundary (corrected mass flow). 3) Wall with no slip condition. For (3) I use isolated boundary for pressure equation (no diffusion through boundary), but I'm not sure what do I have to use for (1) and (2) because I'm confuse if I have to set 0 value for pressure nodes at the exit (let's say a pipe or duct exit) or is it a no diffusion boundary condition on pressure equation. This is a collocated variable CVFEM scheme on triangular grids... Best regards... |
